In response to the "Action Plan for promoting the large-scale deployment of Internet Protocol version 6 (IPv6)" issued by the two offices last year, China's leading Internet manufacturer Xinhua San said that the release of the plan is encouraging!

From a policy perspective, we have seen the foresight and foresight of the new generation of national leaders. Throughout the world, the United States began to implement IPv6 commercial testing in 1996, and began to operate and use it from the Pentagon. Today, the number of IPv6 users in the United States has grown to 100 million, accounting for 38% of the total Internet users. Among the countries with the top 10 IPv6 penetration rates in the world in 2017, Western European countries occupy seven seats. The number of IPv6 users in India in Asia is as high as 220 million, the largest in the world. However, China's IPv6 lags behind, and its development is extremely urgent.

From the perspective of content, we can see the thoughtfulness and foresight of national managers, which have made overall consideration from five aspects: Internet application, network infrastructure, application infrastructure, network security, and key cutting-edge technologies, and formulated detailed IPv6 evolution goals and long-term plans, providing important guidance for the promotion of national IPv6. For a long time, the stagnant application of IPv6 has been an important factor restricting the development of domestic IPv6 promotion. The release of the "Plan" attaches importance to the development of IPv6 applications, and the traction and guarantee of policies make us full of confidence.

The Action Plan clearly requires various industries to implement it conscientiously, among which operators, IDC, CDN and cloud service providers, as providers of the Internet feast, are responsible for delivering high-quality network resources to thousands of households. As an infrastructure provider of Internet content providers, Xinhua three is duty-bound to implement the action plan to the end. During this period, the IPv6 upgrade of the user network has also put forward new requirements for Xinhua San. how to continuously provide high-quality solutions and products and services from the aspects of product research and development, production and delivery is a new issue that Xinhua San faces.

There are not only addresses, but also opportunities and challenges.

Since the 21st century, the transformation and impact of the information technology revolution on traditional industries can be highly summarized by the word "subversion". With the development of enterprise business, the shortcomings and limitations of IPv4 protocol itself are gradually exposed, which gradually become a major obstacle to the development of enterprise applications, and network operation and maintenance is suffering.

Compared with the network security brought by IPv4,IPv6, there are many aspects. First of all, the huge address space meets the address allocation needs now and in the future decades or even hundreds of years, and every Internet user and device can obtain at least one IPv6 global unique public network address. Internet access no longer depends on NAT,IPv6 address, just like a "network ID card", which uniquely identifies each user, which brings great improvement to the work of security traceability. It is more difficult to attack the network layer by means of exhaustion, traversal, scanning and so on.

Secondly, the end-to-end security encryption built in the protocol has been greatly improved compared with the function of IPv4 security protection, which reduces the security risks of enterprise information theft and hacker attacks brought by network security. Finally, because the attack of the application layer does not have much correlation with the IP layer, the protection of the application layer still maintains the efficiency and accuracy of IPv4.

The improvement of IPv6 in the agreement undoubtedly makes the cumbersome IPv4 coruscate new vitality and brings more possibility and reverie space to enterprise users. Of course, at the present stage, IPv6 still belongs to a blank field that has just been opened up for most Chinese enterprises, and the commercial profit model is not yet clear, which is destined to be a long-term evolution process.

How to upgrade IPv6 with minimal cost?

First of all, Chinese enterprise users must deeply realize that the transformation of IPv6 is an investment, not a cost. Secondly, in the transformation of IPv6, we should have an open mind to accept the application of new technology, rather than stick to the traditional way. Finally, the upgrade and transformation of IPv6 is not a simple project achieved overnight, it is more a slow and gradual process, which requires the adaptive support of a series of products, such as applications, networks, terminals and so on.

At the protocol level, IPv6 and IPv4 are peer-to-peer protocol systems, so the network transformation of IPv4 is basically a stable and smooth process, and there is only additional IP investment in some locations, such as servers, storage and other infrastructure that does not support IPv6. In fact, as early as a decade ago, many IT devices already supported IPv6. According to the 2017 IPv6 support report, many major server manufacturers (including storage, tape libraries, etc.) have completed IPv6 Ready certification and have IPv6 service capabilities. From the point of view of the current system transformation, the use of tunnel and AFT technology, while the network deployment of dual-stack protocol is the most economical and reliable transformation. The transformation is smooth, compatible and adaptable, and the network is flexible, which can meet the basic needs of long-term evolution.

IPv6 contains great commercial value.

If IPv4 is a huge mineral deposit that has been discovered and developed, then IPv6 is the sea of stars, and its huge commercial value is waiting for tens of thousands of people to develop and explore. For a long time, Xinhua San has been carrying out continuous R & D investment and in-depth research on IPv6 technology, and hopes to contribute to the promotion of IPv6, achieve the largest number of users' value, and provide maximum convenience for it. In fact, from the earliest CNGI, Cernet network testing, construction, Xinhua San has been actively involved in IPv6 testing, research and development, almost all network products have supported IPv4 and IPv6 dual-stack deployment capabilities, the main products have passed the IPv6 Ready certification, a wide range of services in all walks of life.

At present, all the network products of Xinhua San basically have the ability to support IPv6 protocol and application deployment, from switches to routers to wireless, Internet of things and other products, each product has been filled with IPv6 capability from the beginning of the pipeline. For users, IPv6 is not a paid patented technology, but a basic network service that everyone can enjoy and "consume" for free.

During the development of IPv6, Xinhua Group has continuously invested in research and promoted its construction, for example, working with Tsinghua University to explore the construction of the next generation education backbone network, actively participating in the research and development of frontier characteristics based on IPv6, and so on.

The influence of IPv6 on the Internet Power

Whether it is the Internet of things, smart city, or industrial Internet is a systematic and complex project, hundreds of millions of terminals and sensors will be connected to the IP network, but this is far from enough for all 4.3 billion addresses of IPv4 (private network, multicast, reserved addresses are not considered). The development of IPv4 promotes the birth of technology giants such as Microsoft, Amazon, Apple, Google, Alibaba and Tencent, while the progress of information technology feeds on the public and brings earth-shaking changes to the life, entertainment and study of ordinary people. In fact, compared with a wide range of Internet applications, IPv6 is a basic resource, just as engine manufacturing needs rare earths and everything needs water to grow. For the retention and use of IPv4 seems to be an invisible "arms race", the major Internet companies are in advance layout. The emergence of IPv6 perfectly solves the shortcomings of IPv4. In the past few decades, the Internet trend has swept the world, and the technological dividends enjoyed by western developed countries are visible to the naked eye and needless to say. At present, the development and application of IPv6 in China plays an important role and significance for industrial reconstruction. With the thunderstorm in the Internet world and the increasingly fierce national competition, IPv6 may be the next industry tuyere, and everyone needs to keep a high degree of attention.
